XPC860SRZP33C1

Overview

The MPC860 is a 32-bit embedded microprocessor from Motorola's PowerQUICC family, designed for broadband access and data communication. It integrates an Embedded PowerPC core with a Communication Processor Module (CPM) to handle high-level code and low-level communication tasks respectively. The processor supports multiple serial controllers, cache configurations, and network protocols. Key modules include the PowerPC core, System Interface Unit (SIU), and CPM, which features a RISC controller, dual-port RAM, and various serial interfaces like SCC, SMC, SPI, and I2C.

Feature Summary

• Dual-processor architecture combining an Embedded PowerPC core for high-level execution and a 32-bit RISC processor within the CPM for low-level communication management.
• Integrated Communication Processor Module (CPM) that offloads peripheral tasks from the main CPU, reducing overall power consumption compared to traditional architectures.
• Comprehensive set of serial communication controllers including SCCs for Ethernet and HDLC/SDLC, SMCs for UART modes, and support for SPI and I2C interfaces.

Applications

• Broadband access devices such as routers
• Access hubs and LAN/WAN switches
• PBX systems
• STM gateways

Procurement Notes

Verify the specific suffix 'SRZP33C1' against official Motorola documentation to confirm clock speed, temperature range, and package type. Ensure compatibility with existing system bus requirements and voltage levels. Cross-reference the part number with current datasheets to confirm availability and any potential obsolescence notices or lifecycle status changes.

Selection Notes

Select this component when designing systems requiring integrated communication processing capabilities alongside a powerful RISC core. Consider the MPC860 for applications needing flexible serial interface options and protocol support without external controllers. Evaluate the power consumption benefits of the dual-core architecture against performance requirements for network handling tasks.

Part Context

The MPC860 belongs to the PowerQUICC family, representing a next-generation evolution of the MC68360 in the networking domain. It offers improved adaptability, scalability, and integration levels. The device is specifically engineered to meet the demands of modern data communication environments by providing on-chip resources for common control peripherals.
